I have 2 almost identical files (one sheet about 70 pages each)
I view them side by side and sometimes (NOW) it will not let me scroll synchronously..
It will when I view them stacked.
No other excel open.
I have saved both... closed down and restarted...
still no go, it was working 1/2 hour ago.

The View Side by Side option works.. but the "scroll synchronously" button will not let me highlight it.. as well as the "reset window position" button.

HELP!

Thanks
